Stage 1: Paste any product URLProcessing...

Three steps. Zero learning curve.

No briefs to write, no editors to hire, no templates to configure.

Step 1

Paste your URL

Drop in any product URL. Protagon's browser captures screenshots, features, and positioning automatically. No manual input needed.

Step 2

AI creates 5 variations

Each with a different hook, structure, pacing, and CTA. Diversity enforced. 30% exploration guaranteed. No two videos feel the same.

Step 3

Review and post

Videos arrive with titles, captions, hashtags, thumbnails, and reply bait. Quality-scored. One-click download. Just post.

What you get

5 videos. 3 formats each. Ready to post.

This is real output from one URL. Not a concept. Not a pitch deck.

The email problem nobody talks about

What's your email delivery rate? Genuinely curious.

The honest math

You will not win posting 1 video per week.

The founders outgrowing you aren't more talented. They just post more. Consistently. On every platform. We've all been there.

Your competitors can't copy this

Your Protagon account is a moat.

Every video you approve or reject feeds back into your engine instance. It learns which hooks your audience responds to, which pacing works for your niche, what tone matches your brand.

A competitor signing up today starts from zero. You're already ahead. Every video you generate makes your next one harder to compete with. This isn't a tool — it's an arms race. And you're winning by using it first.

Learns which hooks work for your audience

Adapts pacing and tone to your niche

Scores improve as you approve and reject

Your learning data is never shared

Built for founders who ship.

Everything you need to turn product URLs into a content machine.

Variation Engine

5 distinct videos per URL, not cosmetic tweaks. Different hooks, structures, pacing. Every video is unique to your product — these aren't templates, they're yours.

Hook-First

Every video opens with a scroll-stopper within 2 seconds. Features come after attention. Because nobody watches a video they scrolled past.

Distribution-Native

Title, captions, hashtags, thumbnails, reply bait — all generated. Every asset you need to post on any platform. Just download and publish.

Quality Gate

Not every video hits. That's why we generate 5 and score all of them. Hook impact, pacing, visual rhythm, novelty — anything below 70 gets auto-regenerated. You only see the good ones.

Learns Your Audience

Every approval and rejection trains the engine on your brand, your audience, your niche. Week 8 output demolishes week 1. Your competitors can't copy this.

Questions

Everything you need to know about Protagon.

Short-form marketing videos (15-60 seconds) designed for social media distribution. Four templates: Launch, Problem-Solution, Feature Spotlight, and Controversial Hook. Each optimized for engagement — hook-first, fast-paced, with voiceover and captions.
A single URL with 5 variations typically completes in 3-5 minutes. The pipeline runs screenshot capture, AI analysis, script generation, voiceover synthesis, and video rendering in sequence. Batch mode processes 6 URLs in parallel.
No. Videos arrive fully rendered with voiceover, captions, transitions, and thumbnails. The quality gate scores every composition before rendering — anything below threshold gets automatically regenerated. You review and post.
Three formats per video: 16:9 (YouTube, Twitter), 9:16 (TikTok, Reels, Shorts), and 1:1 (LinkedIn, Instagram feed). Pro and above get all three. Free tier gets 16:9 only.
Yes. Each URL is independent — paste any product page, landing page, or feature page. Batch mode lets you process 6 URLs at once. Scale and Enterprise tiers are built for multi-product content factories.
Every video you approve or reject feeds back into the engine. It learns which hooks resonate with your audience, which pacing works for your niche, and what tone matches your brand. The more you use it, the sharper it gets. This isn't a static template tool — it's a learning system trained on your specific audience.
Every video passes a multi-dimensional quality gate: hook impact, pacing rhythm, visual coherence, and novelty score. Videos scoring below 70/100 are automatically regenerated (up to 2 retries). The engine improves over time as it learns what performs.
